This invention relates to valve construction, and more particularly tovalves of the float actuated type.

An important object of the invention is to provide a valve of thischaracter comprising a body portion of a construction to insure aperfect seating of the valve, under varying degrees of pressure.

Another object of the invention is to provide 10 a self balancing valvemember mounted in such a way that the water pressure entering the tankin which the valve operates, will act to alignthe valve with its seat,to further insure thetrue seating of the valve.

15 A still further object of the invention is to provide a support forthe valve which will increase the leverage of the valve actuating arms,with the result that the lengths of the valve operating arms andconnecting links may be greatly 20 reduced.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of con- 25 struction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein described, may be made within thescope of. what is claimed, without departing from the spirit of the in-30 vention.

Referring to the drawing:

Figure l. is a side elevational View of a floatactuated valveconstructed in accordance with the invention.

35 Figure 2 is plan view thereof.

Figure 3 is a sectional view taken on line 33 of Figure 1. I

Referring to the drawing in detail, the reference character 5 designatesan inletpipe through 4 which water enters a tank or the like container.The discharge end of the pipe 5 is reduced, pro- Viding a valve seat.

Pivotally mounted on the inlet pipe 5, at a point directly below thereduced end thereof, is a yoke 4 ii that fits around the discharge endof the pipe, the yoke including spaced arms 1 between which the'lowerend of the link 8 is pivotally mounted.

upper end of the link 8 is pivotally mounted between the arms 9 thatextend over the discharge end of the pipe 5, as clearly shown by Figure1 oi the drawing.

adapted to move into engagement with the rean arm it, to which the arms9 are pivotally connected as at l l. The arms 9 provide the support forthe valve base i2 having an upstanding wide extension 33 which ispivotally mounted between the arms 9, as by means of the pivot pin M,the opening in the extension i3 being of a diameter to allow freepivotal movement of the valve with respect to the arms 9 to insure atrue seating of the valve. 1

Mounted on the circular base i2, is a disk-like valve member I? securedto the base by means of, ascrew. This valve member i5 is constructedpreferably of rubber to insure a true seating of the valve to cut offthe flow of water from the inlet pipe 5.

A threaded opening is formed in the yoke 6, into which one end of therod in is threaded. The float H is secured to the free endof the rod l6and operates to close the valve as the water level in the tank in whichthe valve is positioned, reaches its limit. 3

From the foregoing it will be seen that due to the construction shownand described, I have provided a self-balancing valve which will seatperfectly under varying degrees of pressure and one wherein the leverageof the valve actuating arms will be greatly increased to the end thatthe lengths of the arms of the valve actuating mechanism may be greatlyreduced.

I claim: 1 A float-actuated valve including a tubular body portionhaving a reduced discharge end providing a valve seat, a yoke positionedover the body portion and pivotally connected thereto, a link pivotallyconnected to the yoke and extending upwardly beyond the end of; the bodyportion, an

upwardly extended arm connected with the inlet pipe, a pair of armsconnecting the first mentioned link andsaid upwardly extended arm, saidpair of arms normally lying in a horizontal position, a valve member, awide extensionv rising from the valve member, said wide extension beingpivotally mounted between said pair of arms, a disk-like valve mountedon the valve member and duced end of the body portion, for controllingthe flow of. water through the body portion, and a rod carrying a float,secured to said yoke.
